Zabco, i hadn't noticed them either, but i'm also not in horse country. i'll show my work
My phone won't show exif data on an image, so i don't know where it was taken. I found those trailer pics on Reddit, with a couple people saying not-fake, but old and very rarely used. Then while searching for more horse trailer info i found a total of 3 pics, all of the same trailer! (Fleet number 3666 SO 8133, which has a Georgia plate in a pic)
That Georgia farm plate is odd since almost all of Uhaul fleet is plated to Arizona
I mean is it weirder to go around taking pics of fleet vehicles to post on the internet, or weirder to paint your own outfit in a rental livery? Then several horse owner sites popped up mentioning 'renting a u-haul horse trailer' maybe it's a thing, could be the "All 'facial tissue' = Kleenex" thing, could be search engine optimization bs...
Well, i still liked the idea and thought that seemed plausible as close enough to real to make a toy fake one? So working off the rental company "seems to have run a few of those", and that the toy company "could have produced those with existing parts" was close enough for my destructive tendencies.

Then since you asked, it looks like there are only 5 locations in California and New Mexico that have horse trailers available as of 2021?

Don't worry instead of an inop rats nest of wiring, none these are even getting lights! Just some rhinestone reflectors.
